A/9=-4 One-step equations
worty [1.4K]
A=(-36). When finding variables, try multiplying the quotient and divisor to get your dividend. Also, when multiplying/dividing negative integers, if there is one negative integer, the answer will be negative. the only exception is when multiplying/dividing two negative integers, then it would be positive. -36/9=(-4)

2. Evaluate f(x) = 3x+5/x-1<br> at x = 3
pashok25 [27]

Answer

Let f(x) = ax + b

Then

f(x + 1) = a(x + 1) + b

= ax + a + b

Hence, a = 3, and a + b = 5, b = 2

f(-2) = 3(-2) + 2

= -6 + 2

= - 4

f(2x) = 3(2x ) + 2

= 6x + 2

Help solve for r algebra
bija089 [108]

Answer:

\frac{20}{7}

Step-by-step explanation:

Multiply both sides by 7 to get rid of the denominator on the Right Side (RS). Do the same for the left side (LS) by multiplying both sides by 5 to get:

7r=4(5)

Simplify: 7r=20

Divide both sides of the equation by 7 to get: r=\frac{20}{7}

(7s – 8s⁴ – 3) + (-4s – 6s⁴ – 2s²)
klasskru [66]

The simplified expression is: -14s⁴-2s²+3s-3.

First group all the like terms together.

(-8s⁴)+(-6s⁴)=-14s

-2s

7s+(-4s)=3s

-3

Then put the expression back together, starting with the term that has the largest exponent, then working your way down. You would then get: -14s⁴-2s²+3s-3.
